“The Vampire Diaries” star Nina Dobrev was fiercely competitive during the DirecTV Celebrity Beach Bowl on Saturday — especially as her boyfriend and co-star Ian Somerhalder was on the opposing team. The mixed celebrity teams played flag football at an indoor beach. But one onlooker said, Deion Sanders would not throw the ball to Nina, even when she was wide open, and she was getting pretty frustrated. The onlooker said, “It didn’t seem like Deion wanted to pass to the girls.” Other stars in the game included Snoop Lion, model Chrissy Teigen, Chace Crawford, Maria Menounos, Derek Jeter’s girlfriend Hannah Davis, Jenny McCarthy, Matt Bomer, Artie Lange and former NY Giants Jesse Palmer and Amani Toomer. The game ended in drama when Lil’ Wayne got into a confrontation with an onlooker on the sidelines before he had to be held back by security. His rep didn’t get back to us last night.
